So I want to redo this wiring hack job on my World Fair. Someone had cut the harness going to the head, spliced in a different Jones plug with different color wires and used butt connectors. It works but I hate it. I bought a scrap harness on eBay and have all the correct colors to match. The plan is to match up the correct colors and solder and shrink wrap new splices. However I’m not having much luck getting the wires to hold inside the Jones plugs. I’m trying to some fresh solder inside the plugs, tin the ends of the wires and then heat the plug. It’s not working great. Some are holding, some are not. Anyone have any experience redoing these? Any tricks to doing this correctly? Thanks
